My first breath was just...it just seemed impossible that you could actually breathe underwater. I knew in my mind it was possible, but actually experiencing it was such a gulp of joy and I feel it every time I go under the ocean. I love doing it, to be able to feel weightless, to spin on one finger, to do somersaults, to be like a graceful ballerina - even with a huge tank on your back you can do the most extraordinary things.

Ironically the very energy, the very basis of how we know what we know, has been reliant on having an energy source [necessary] to build rockets to go to the moon and Mars, to support airplanes that fly, and satellites to give us our communication.

I personally have stopped eating seafood.

Even if you never have the chance to see or touch the ocean, the ocean touches you with every breath you take, every drop of water you drink, every bite you consume. Everyone, everywhere is inextricably connected to and utterly dependent upon the existence of the sea.

We couldn't go to the moon on whale oil. We don't have the capacity yet to consider doing such things as harnessing current sunlight. We're burning ancient sunlight in order to get us to where we now are. But it's costly.

If you think the ocean isn't important, imagine Earth without it. Mars comes to mind. No ocean, no life support system.

This much is certain: We have the power to damage the sea, but no sure way to heal the harm.
